Application me much 4, 1915. Serial No. 12,014

To rill whom it may concern:

Be it known that I, LINFoRn S. S'rrmis, a citizen of the United States, and resident of Brook 11, county of Kings, and State-of New Yor have invented an Improvement in Cinematographs, of which the following is a specification, I a J v The object of my invention is to provide a moving picture machine of the cinematograph type which may be adapted for educational purposes, and more particularly for teaching dancing-or other qualification in which certain movements or steps are required; for example, aside from the special dancing steps, the pictures ma glve exercising movements such as dun1 '-bell, fencing, and other exercises well known to those interested in athletics whether for sport or whether for health purposes, such as flesh reducing exercises, etc. 4 I

While the above are the primary .objects of the invention, my improvements are also adapted for cooperation with a talking machine by providing a flexible detachable power transmitting connection from a ro tatin'g part of the talking machine, whereby ate the cinematograph; and m this connection it is evident that the cinematograph may beemployed to illustrate a dance while the Victrola is operated toplay the dance music. To permit-the timing of the dance to the music,I provide means on the cinematograph under the control ofth'e operator to change the speed of the picture film to suit the speed of the music. It'will furthermore be understood that my object is to enable the person operating the cinemat ograph to not only permit the machine to run in a continuous manner. to ive the appearance of'motion, but the 1m may stopped at any time so that any particular position illustrated in the] picture may be 1 carefully studied. In this manner, the operator has the power to seethe individual positions as if they were ordinary photographs, and also has the power to see the positions in such rapid succession that the actual, motions of the natural exercises a a bracket 14 in whlch the shaft is also jourwould be apparent.

With these and other objects inview, my I invention, consists of certain novel features of construction of the cinematograph and ts adaptability for connection with a talkmg machine, all of which are fully set out hereinafter and more particularly defined -'1n the claims. My mvention will be better understood by'reference to the drawings, in which Figure 1 1s a rear elevation of my cineplan view of the same;'and' Fig. 3 is an elevation of part of the driving mechanism.

'2 is the case andis adapted to stand upon a table or any other convenient support.

may be opened for purposes of providing --matograph apparatus; Fig. 2 is a sectional This case may have a hinged back 3 which access to the interior and especially for replacing the. endless film. A snap catch 'orother fastener 5 may be employed for holding the'back in closed position. Arranged within the case are the two drums '6 and 7,

the latter being supported on a fixed axis, while the former is provided with ashaft 8 .journal'edin an adjustable "bearing 9 and spring pressed by a spring 11 so as 7 to move the drumfi away from the drum w adapted to slide in a suitable guideway 10- drums to be moved relatively towardeach other when it is desiredto replace the film by another film. These drums may be provided with sprocket'teeth and the films with sprocket holes, as is common in cinematograph and moving picture machines. I do not restrict myself in this regard. The sprocket drum 7 which is the driving drum is provided with a shaft 1 2 journaled 1n a bearing 13 and having its lower end slidably connected with the hub'of a friction wheel.

17, whereby it may be rotated by said frictionwheel and atthe same time said fric tion wheel may be adjusted longitudinally ofthe shaft. The rotating connection may be by a spline or any other suitable Well known device which will positively rotate the shaft by the rotation of the friction wheel. The friction wheel 17 is journaled in guided vertically in the case 2 at 15.

naled, as will be clearly understood by reference to Fig. 2, and this bracket 11 is A. spring 18 surrounds the shaft 12 and presses at one end upon the fixed bearing 13, and

being secured to the arbor of the motor to permit winding thereof. A motor for this purpose would be of that type which is provided with a proper escapement device, such as a governor, tO,'CO11t1Ol its speed. Such motors are very common in talking machines 'and music boxes, and I therefore do not limit myself to any particular construction of the motor. The driving friction wheel 22 of the motor is in position to engage the perimeter of the friction wheel 17 when the latter is pushed axially by the push pin 20, slidably carried in the case in alinement with the hub of the friction wheel 1? 'lVhen the friction wheel 17 is pushed in contact with the driving friction wheel 22, the spring 18 is compressed and the bracket 14 is moved upward. As long as the push-pin 20 is held in, the sprocket wheel 7 will cause tliefilm 38 to be made to travel under the eye-piece 10 which may be provided with the usual lenses, and by which the pictures on the film may be viewed. The usual lamp and reflector maybe arranged below the film. A shutter 25 may be employed as part of the whole mechanism to intermittently expose the pictures successively when they are squarely under the eye-piece, so that the impressions of the pictures come in rapid succession upon the eye for less than the whole period of movement of a picture under said eye-piece. The shutter may be driven by any suitable mechanical device such as a sprocket chain 26, so as to be in timed relation with the revolutions of the drum 7 which propels the film to make an 1 intermittent exposure so as to expose each to study the positions of objects, such as dancers on the film. He has therefore the power of starting and stopping the film at will. If the film is to be run continuously, the adjusting screw 16 will be screwed up against the bracket 14 until the friction wheel 17 is maintained in contact with the friction wheel 22. It will also be understood that the film may be driven at different speeds by simply adjusting the screw 16 to allow a slight separation between the friction wheels 17 and 22, and then by a sensitive pressure upon the push-pin 2O varying the frictional contact between the saidfriction wheels. By this hand adjustment, the operator may movethe film at full speed or at a slower speed or intermittently stop it, and thereby be able to study the motions and positions of the objects by which they are accomplished. In this way, a person v may study a new dance and analyze it thoroughly. The same results may be accomplished with any form of exercise depicted upon the film, so that the device becomes an educational one; The films are preferably formed of an endless band of transparent material such as celluloid and commonly employed in cincmatograph and. moving picture machines. By having the two drums 6 and 7 adjusted relatively to and from each other, it is manifest that by opening the hinged back 3, the endless film 38 may be readily removed and a new film inserted and instantly put under tension by the action of the spring 11. While I prefer to employ endless films for the obvious reason that they are easily applied and removed, it will be understood, however, that for some special uses where a greater number of exposures of the pictures are required, the film may be arranged in any other suitable manner.

In connection with the apparatus herein described, driving mechanism may be provided to rotate the film from a rotating part of an ordinary talking machine, and this is illustrated in Fig. 2 by mechanism comprising the following construction J ournaled in the case 2 is a shaft 27 having upon the inner end a small friction wheel 28 against which the driven friction wheel 1.7 may be pressed by the spring 18 when permitted to do so by the adjust-meutof the screw 16. The contact position is shown in Fig. 2. Clamped to the end of the shaft 27 where it extends through the casing, is a coupling 30 which connects with one end of a flexible shaft 29. The other end of this flexible shaft is secured to a bevel pinion 81 which meshes with a bevel gear 32 having a rubber bushing 34 that may be crowded over a rotatable part of the talking machine. As shown, it is crowded over the hub 35 of the turn-table which carries the record. The end of the flexible shaft adjal 20 20, may befreleased and the mechanism i cent to the pinion 31 is journaled in a bearlatter holds them in proper relation. In this manner, the cinematograph machine may be readily connected Witli a talking machine and drivenby its motor, and atthe same time, the cinematograph" will have all the,

provisions forcontrol which have hereto;

fore been described. hen connected with v 'a talkinglmachine, suitable music may be provided'whilethe cinematograph is qperating, as will be well understood.- In

'22 of motor 21, and after the op eration with the talking. machine, the dancing pictures lag, theymay be speeded up by pressing the button friction wheel 17 into. contact with the wheel "an ced to catch up'to the music, the button driven from the talking machine as before. While a talking machine is an available source of power, irrespective of the accompan'y-ingjmusic, the flexible shaft and the terminal gears may be adapted for connection with any other suitabie motor device that is available, andthe flexible shaft permits the positioning of the cinematograph device for convenience in Watch ng the film. I have shown my invention in one form as i to its details, but it is to be kept. in mind that the power transmitting devices between I vthe motive power and the film may be va-' ried greatly, and I therefore do not restrict myself to the details asthese may be modified in various ways without departing from the spirit of the invention. Having now described my invention, what I claim-as new and desire to secure by Let ters Patent, 1s
